Output characteristics

If the input data consists of 13 bits or more, only the lower 12 bits will be valid, and the other bits will
be ignored.

Insulation method

• The photocoupler is used to insulate the analog output area from the PLC.
• Channels are not insulated from each other.

Number of I/O points 
occupied

8 points (Taken from either the input or output points of the PLC.)
